Applicable for three-hose machine cutting torches only. With a two-hose cuting torch,
preheat pressure is set by the cuttting oxygen.
** For best results use HC1200C series torches and 3/8" hose using a size 6 tip or
larger.
*** All pressures are measured at the regulator using 25' x 1/4" hose through tip size 5,
and 25' x 3/8" hose for tip size 6 and larger.
